This technique was first proposed by Horace Babcock, and this technique allows systems to approach the Fried coherence limit. Fried and Greenwood also derived the bandwidth limit for systems that implement this technique, which can correct one Zernike mode per actuator. One operation necessary for performing this technique is accomplished through the use of the Shack-Hartmann procedure; that operation is wavefront sensing. This technique relies on the presence of a guide star as well as the object to be imaged and a fast-steering mirror which removes aberrations induced by the tilt. The use of this technique allows large mirrors to achieve diffraction-limited imaging. For ten points, identify this experimental techn

For ten points, identify this experimental technique which utilizes a deformable mirror to remove phase distortions induced by atmospheric turbulence.
